Mold Only - Additional Filters

Testing more than one room? Add an extra filter to test for mold in an additional space (up to 1,000 sq ft) — ideal for basements, attics, or additional bedrooms where mold is a concern.

Uses the same easy at-home collection process as your Mold Only Test Kit. Place the fan + filter in the additional room, then ship it along with your other filter(s) in the same prepaid mailer for lab analysis.

Note: This add-on requires an existing Mold Only Test Kit order — it's a filter only, not a standalone kit.
